This adds the required bits to the ipu-v3 and imx-drm driver to make scanout of the Vivante (super-)tiled single buffer format work on i.MX6 QuadPlus. A userspace taking advantage of this support is able to skip the linear resolve step in the GPU, saving quite a lot of memory bandwidth especially with higher resolution displays. The first 3 patches can go in as-is, while the last patch depends on Ben Widawsky's series to add a format modifier blob property to the DRM planes.
